PATENT BERNARD JOSEPH GIEBEL AND XVILLIAM ARTHUR PARK, OF FREMONT, OHIO.

SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 653,799, dated July 17,190i).

Application filed M 1 4, 1899- Renewed March 8, 1900. Serial No. 7,928.(No model.)

To ctZl whom it may concern.-

Be it known that we, BERNARD JOSEPH GIEBEL and WILLIAM ARTHUR PARK,citi- Zens of the United States, and residents of Fremont, county ofSandusky, and State of Ohio, have invented certain new and usefulImprovements in Locks, of which the following is a specification,reference being had to the accompanying drawings, forming a partthereof, in which similar characters of reference indicate correspondingparts in all the figures.

This invention relates to improvements in seal-locks; and the objectthereof is to provide a device of this class which is so constructed asto prevent tampering therewith without leaving evidence of suchtampering.

The invention will be hereinafter fully described, aud specifically setforth in the annexed claim.

In the accompanying drawings, forming part of this specificatiomFigure 1is a front elevation'of our improved lock having a portion thereofbroken away. Fig. 2 is an end elevation. Fig. 3 is a sectional plan Viewon the line :0 of Fig. 1. Fig. 4 is a longitudinal sectional elevationon the line 3 y of Fig.3. Fig. 5 is a face view of one of the platesforming part of the device. Fig. 6 is a face view of a seal used incombination with the device, and Fig. 7 is a side elevation of a keyadapted for operating the look.

In the practice of our invention we employ ordinary locking meanscomprising a springactuated hook A and a cross-bar b for engagementtherewith, the bar forming part of a casing B, which is secured to theframework of a structure to which the device is attachedfor instance, afreight-oarand the hook A being mounted within a casing C. This saidhook is pivoted upon a spindle Ct, which projects from the inner wall ofthe said casing O, and it normally rests upon alug to", also projectedfrom the said rear wall of the casing, and the hook is maintained in anormallyhorizontal position by means of a plate-spring D, secured to aprojecting lug d of one end wall of said casing. The said mechanism iscovered by means of a partition or plate E, located back of the frontwall 0 of the casing O, and a horizontal keyhole c is supplied throughthe said plate for guiding the key which operates the locking mechanism.Between the plate E and the front Wall 0 of the casing O is a recess e,which'is formed by means of a rib 6 extended from the face of the plateE, and this said rib bears against the inner face of the front wall 0 ofthe casing O. This said recess is adapted for retaining a seal 1, aswill be hereinafter described.

The front wall 0 of the casing O is supplied with an aperture 0', whichhas recesses 0 extended therefrom for guiding the key, these saidrecesses exactly registering with the horizontal portion of the keyholec. This aperture is of a considerably-larger diameter than the keyholefor the purpose of exhibiting the seal 1, contained within the recess 6.The seal is composed of fragile material, preferably paper, and it isprovided upon one corner thereof with an extension 2 for the purpose ofremoving it and for placing it in position. The seal may also besupplied with any suitable printed matter upon the space 3, which isvisible through the recess e.

The several parts of the lock-casing are held together by means ofscrews 4, which engage studs or projections 5, forming part of the rearwall of the casing, and the device is adapted to be attached to acar-door by means of screws,which maybe passed through the apertures 6,formed through the walls of the casing, similar apertures being formedthrough the plate E. The casing for engaging the hook when the door isin alocked position is also provided with apertures 6 for receivingscrews for fastening the same to the framework of a car.

To prevent the lock from being manipulated without the use of a properkey, annular projections 7 are formed around the post 8, and these saidprojections engage recesses 9 of the key 10. A

The casing B is provided with a flange or extension 19', which laps overone edge of the front wall a of the casing O to prevent tampering withthe seal, and the whole face of the said front wall 0 is covered, bymeans of a hinged plate 0, to prevent the seal from being injured bymoisture during inclement weather. In the operation and use of thedevice-for instance, when it is placed upon a car-doorwhen it is desiredto lock and seal the car it is simply necessary to place a seal 1 withinthe aperture c and close the door, which, owing to the construction ofthe lock, will fasten automatically. Then in order to unlock the same itis first necessary to fracture the fragile seal before the key can beinserted, and it is obvious that should said seal be fractured bypersons without authority the act can be readily detected.

We do not confine ourselves to the specific details of mechanicalconstruction as herein shown and described, as it is obvious that underthe scope of our invention we are entitled to variations, and ourinvention can be employed in combination with any springlock.

Having thus described our said invention, what we claim as new, anddesire to secure by Letters Patent, is-

In a seal-lock, the combination of a casing embodying afront platehaving anaperture therein, an auxiliary plate located back of said frontplate and having a keyhole which registers with the said aperture, arecess between the two said plates, a fragile seal contained within thesaid recess, and having the end portion projecting from said recess, andthe supplementary casing having the flange or extension which laps overthe edge of the front wall of the main casing and covers the projectingend portion of the seal, substantially as shown and described. V

In testimony that we claim the foregoing as our invention we have signedour names, in the presence of two witnesses, this 21st day of February,1899.
